Molex device chaining

Just wondering if theres any reason to avoid chaining devices together across the same segment of molex connectors. i.e. i have 2 ata harddrives and a 6800GT card all connected on a 3 molex equipped piece of wire. Does electricity just all run the same anyway or something so it doesnt matter? or should i use seperate pieces of wire for critical devices?
 
I am pretty sure that you need to keep your 6800gt on a seperate wire chain, by itself.
 
or what, what are you gonna do, huh? You gonna sick the dogs on me? Or the bee's? Or the dogs with bee's in their mouth and when they bark they shoot bee's at you? Bump...
 
Do a google search on PC power supplies, esp in regards to "Rails"

Power supplies have total power output, and they also usually have that total output divided into rails, which is just a subdivision of the total. Each rail also has a max output. Since a device like a GF6800 sucks a lot of juice, its in your best interest to put it on its own rail

dogs barking shooting bees, LOL thats funny

no I'll beat you liberally with a clue by four :p
dont go off on people that are trying to help you
or more accurately post jokes that could possibly be interpreted that way ;)

we have more than our fair share of hotheads here

a few graphic cards are now recommending a dedicated wire branch of the harness
as far as "rails" goes, a rail is the common voltage rails (+3.3V, +5V, +12V)
they arent seperated by wire branch\strand
the concern is that added devices on that strand could cause fluctuations if Im not mistaken,
since the total amps a typical 18AWG wire can handle is far above the draw of the combined devices

generally that is correct,

and would likely still be correct with a high quality power supply
but then recommendations are often of the lowest common denominator type

actually, you will get either:
(a) a very, very unstable video card, or
(b) a melted psu.

why don't you just switch the voltage on the psu to 220v right now and see if you get enough current out of the molex connectors? you shouldn't even have to turn it off.

heh heh heh... let's see if he actually does it...

that's the very site i got that idea from... hehe... i still hope he tries it...
umm... anybody think he's stupid enough to do it?
 
You need to have your 6800gt on a seperate chain all by itself with nothing else connected in that chain.
